State Of Emergency

March 15, 1986

SANTIAGO, CHILE — Chile's military government has kept tight control on civil rights since 1973 except for a seven-month break in 1983. It extended the restrictions Friday for three months. People can be detained for as long as 20 days without charges. Government opponents can be kicked out of the country or banished to remote areas. The government did lift a ban on news coverage of non-Marxist political parties which are illegal but tolerated. Independent editors were unimpressed. ''The only change is that it is now no longer a crime to do what we are already doing,'' said one. Sidelight: In Geneva, Switzerland, the U.N. Human Rights Commission called Friday for an immediate end to the use of torture by Chile's security forces. It also expressed concern at continuing ''serious violation of human rights in Chile.''
